Levitate: if used on unwilling target, how often can they save?

@JeremyECrawford #dnd Regard Levitate: if used on unwilling target, how often can they save? RAW says just once, but duration is 10 min.

The levitate spell lets an unwilling target make a single saving throw against it. #DnD https://t.co/XSprYrETdN
